Vacheron Constantin Historiques Chronograph 47101

I always thought 47111 and 47101 has same case size

[@BlackTagWatches]

Not really, different caliber, also case back. One has screws, the other one is snap.

@@BlackTagWatches all Lemania 27ch. Movement size are supposed to be the same. So 47101 is slimmer and smaller in size? What’s the lug to lug?

[@BlackTagWatches]

Based on same 2710, but slightly different movements, look at the bridges. But I think it’s only that. Thickness is the same, 11 mm.

@@BlackTagWatches I know they called it 2320 and 2310 or something like that to have Y and U shape bridges. I might need to look more into the case but I think you stand correct, since screw down case does often goes a bit larger. Did you guys measure the case sizing side by side?

[@BlackTagWatches]

We measured each case with a caliper to verify it. You can find all kind of information online, but we go by what we measure on each particular watch.
